Google has been heavily marketing Android Pay and encouraging users to set it up on their phones with various offers. In the spirit of holiday giving, every time you use Android Pay, from today until the end of December, Google.org will donate $1 to special needs education.

Up to $1 million will go towards projects by DonorsChoose.org to support the 6.4 million children in the US educational system with special needs. On the busy Black Friday shopping day, $2 will be donated with every Android Pay purchase.

Google touts Android Pay as being accepted in over a million locations across the US and working with major banks and credit card providers. Since launch, Android Pay has added support for Citi, but Capitol One is still in the works. Recent Android Pay promotions include getting an Android mini-figure when paying with it at Jamba Juice and winning the chance to attend the Spectre premiere in Mexico City.
